Bash & Shell

leave a comment »

Linux computers make extensive use of shells. Shells are programs that provide text-based user interfaces to the Linux operating system. When working in a shell, the user enters a command plus optional arguments, and the shell parses (separates the various parts of a command into usable parts) and then executes the command. Because shells are used to launch commands (programs), they’re often referred to as the command line interface (CLI).

Bash is the dominant shell in use today within the Linux world. Ubuntu uses bash as its default shell.
